A major Lloyds Banking App glitch triggered widespread concern on Thursday after customers reported being able to see transactions and personal banking information belonging to other users. The issue affected customers using the Lloyds, Halifax and Bank of Scotland mobile apps, all part of Lloyds Banking Group.
Lloyds Banking App Glitch Shows Other Customers’ Transactions
The problem began early Thursday morning when many customers struggled to log into their mobile banking apps. Those who managed to access their accounts reported something alarming — instead of seeing their own transactions, the app displayed financial information belonging to completely different customers.
Users said the glitch allowed them to view transaction histories, account balances, payment records, and personal banking details that were not linked to their accounts. In several cases, people reported seeing multiple accounts during a short period while repeatedly logging in and out of the app.
The issue was reported across apps for Lloyds Bank, Halifax and Bank of Scotland, which together serve millions of customers across the United Kingdom.
Customers Report Seeing Personal Data and Multiple Accounts
Some of the reports highlighted serious privacy concerns. One woman told the BBC she was able to see the accounts of six different users within about 20 minutes while using the Bank of Scotland app.
Each time she logged out and logged back in, the account information appearing in the app changed. She said the details included:
- Names of account holders
- Bank account numbers and sort codes
- Transaction histories
- Payment references
- National Insurance numbers in some cases
The woman also reported seeing benefits payments from the Department for Work and Pensions (DWP). In some cases, the National Insurance number was used as the payment reference.
Other customers described seeing purchases and payments that clearly did not belong to them, including transactions at stores such as Waitrose and payments related to everyday spending.
Full Account Histories and Salary Payments Visible
Some users said the issue went far beyond a single transaction. One Lloyds Bank customer reported that the app displayed the entire transaction history of another account month by month.
That history included direct debit payments, everyday purchases and even payments to the Driver and Vehicle Licensing Agency (DVLA) where vehicle registration numbers were visible.
Another user reported seeing a salary payment of around £6,000 deposited into a stranger’s account, along with references to the company that paid the wages.
In one particularly concerning case shared online, a user claimed the app showed the financial details of as many as 30 different individuals, including names and account numbers.
Social Media Flooded With Reports
The issue quickly gained attention online as customers shared their experiences on social media platforms. Consumer finance expert Martin Lewis said people were messaging him about the banking apps showing other customers’ transactions.
His post on Facebook received nearly 2,000 comments from concerned users who said they had experienced similar problems or feared their own financial information might have been exposed.
Many customers said they initially worried their accounts had been hacked before realizing the issue appeared to be a system-wide technical problem.
Outage Reports Spike on Downdetector
Website monitoring service Downdetector showed a sharp increase in reports of issues affecting the Lloyds and Halifax apps between 7:00 AM and 9:00 AM on Thursday morning.
A smaller spike in outage reports was also recorded for the Bank of Scotland mobile app during the same period.
Customers reported login errors, missing account information and transaction details belonging to other users.
Lloyds Banking Group Apologises
Lloyds Banking Group apologised after the issue became widely reported and confirmed that some customers had been shown transaction information from other accounts.
The bank said the problem was identified quickly and resolved within a short period of time.
A spokesperson for the group said:
“We’re sorry that some customers experienced an issue viewing transactions in the app for a short time this morning. The issue was quickly resolved and we’re looking into what happened.”
The company has now launched an investigation to determine the cause of the glitch and assess whether additional safeguards are needed.
Security Concerns as Digital Banking Expands
The incident has raised fresh concerns about the reliability of digital banking platforms, especially as more banks continue to close physical branches and encourage customers to use mobile apps.
Lloyds Banking Group is the largest retail and commercial banking provider in the UK, serving around 26 million customers across its brands.
With millions of people relying on mobile apps to manage their finances every day, even a short-lived technical error can raise serious questions about data protection, privacy and cybersecurity.
Customers looking for official guidance on financial data security can review resources from the Financial Conduct Authority and cybersecurity advice from the UK National Cyber Security Centre.
Investigation Underway
While Lloyds Banking Group says the issue has now been resolved, the investigation will focus on how the glitch allowed transaction data from some accounts to appear in other users’ apps.
Experts say incidents like this highlight the importance of strict account isolation and robust testing in large-scale banking platforms.
For now, the Lloyds Banking App glitch serves as a reminder that even major financial institutions can face unexpected technology failures in an increasingly digital banking world.
